Application filed February 3, 1922. Ser:lal N0. 533,808.

T0 all wkom z't mag concern:

Be it known that I, KUNZ WEIDLICH, a citizen of Germany, residing Nurmberg, Germany, have invented certa 1n new and useful Improvements in Agltators (1":or Which I have filed an application in Germany, on December 9, 1920), of wlnch the following is a specification.

My invention relates to ag1tat0rs, and more particularly to the kind prowded w1th gearing. In the agitators at present 1n use the stirring blade is rotatably arranged betw=een the feet of a stand which can be pla ced 0n the bottom of the receptacle containing the mass to be stirred. In these devices the shaft of the stirring blade is not only supported in a bearing at the centre or at the t'op end, but also in a further bear1ng arranged in a base plate or cross tie at the bottom of the stand. Owing to this arrange ment the stirring vane rotates at sonne dis tance from the bottom of the Vessel so that it 1s impossible to stir small quantities of a mass such as for instance a single egg yolk.

I overcome this drawback by so arranging the stirring vane that it is freely supported between the feet of the stand so that the lower edge of the vane, which is preferably S-shaped, extends almost down to the bottom of the vessel.

In the drawings aflixed to this specification and forming part thereof a device embodying 1ny invention is illustrated diagrammatically by way of example. In the dravvmgs- Y F ig. l is an elevation, and

Fig. 2 a horizontal seetion on line AA in Fi l.

Re%erring t0 the drawings, a is a frame preferably formed by sheet metal strips. A handle b is secured to the upper end 0f the frame and a plurality of feet c, for instance three, which may be curved and arranged radially, are secured to the lower end. The feet c are connected by a flat ring (Z. M0- tion is imparted to the shaft h of the stirring vane 70 by means of the well known bevel gear f, g provided with anrank e. The S- Y shaped convex stirring vane k is provided with openings z'. y The outer edges of the vane k extend in parallel with the inner edges of the feet c which, as shown in dotted lines at m (Fig. 2) may be V-shaped in cross section.

The vane is freely supported between the feet 0 and its edges move close t0 and past the edges 1 of the feet. This V'-shjaped cross section of the fest prevents the substance to be stirred from spurting up from the receptacle S, inasmuch as it is hurled o'utwards by cen'trifugal action and meeting no resistance has no tendency to spurt up. Ex-

perience has shown that spurting up occurs whenever a liquid or plastie substance encounters a solid resista'nce. S=p1irting upof the substance Which may be hi1rled aga*inst the feet 0 is prevented by the V-shaped ci-oss section of the feet, tl1e radius of the curvature being smaller than that of the pathof the stirring vane. The particles hurled against the edges 1 of the feet 0 are caught in the cavities formed in the feet and are defiected toward the shaft to be hurled' once more outwards by the stirring vane. Thus the novel device not only exerts a hurl ing but also a beating action, andthe massestreated therewith are'therefore 'th'roughly stirred. It may be actuated by handor by power and can be used for homogenizing thinly fiuid and viscous liquids or plastic'massjes, particularly fo-r making mayonnaise 01 Whisked eggs.

I wish to be understood that I do not desire to be limited tothe exact details of onstruction shown and described, for obvious modifications Will occur to a person' skilled in the art.

I claim:

l. In a device of the kind describ d in combinatio1i, a stand, a plurality of fest spaced'apart at the lower end of-said stand,

beating up or ab a shaf't extending vertically in said stand dovvn to the feet and a stirring vane in the x form of a vertically placed piece ofsheet material freely supported at the lower end of said shaft with its bottom ed ge alm0st at a level'with the lowerends of said feet.

2. In a device ofthe kind described in combination, a stand, a plurality of feet spaced apart at the lower end 0f said stand, a shaft extending vertically in said stand down to the feet and a stir'ringvane in the, forma of a vertically placed piece of sheet material freely supported at the lower end of said shart't with its bottom edge almost at a level With the 10Wer ends of said fest, the feet having a V-shaped er0ss-section.

3. 111 a device of ehe kind described in feet having a V-shaped cross-section of 10 combination, a stand, a plurality of feet smaller radius than the circle oi rotation spaced apart at the lower e nd of s2 zid stand of tha stigring vane.

21 shaft extending vertically in said stand In testimony whereof I aifix my signature. down to the feet an l a stirrirw vane in the form of a vertically placgd p iece of sl1e et KUNZ WEIDLICH' material freely supPorted at the lower end of said shaft with its bottom edge almost ab a level with the lower ends of said feet, the
